Site Assessment · £1,000
Scan a site before you sign.
One report, six decisions. Delivered within 48 hours. Built on every comparable small-site decision the borough has made.
Pre-application advice tells you one officer’s opinion, six to eight weeks after you’ve exchanged. A Site Assessment tells you what the borough’s last three hundred comparable decisions actually did, in 48 hours, before you commit.
Six things you get, every time
Risk rating
A Go, Caution, or Stop signal grounded in what comparable schemes in your borough actually achieved. Backed against every decided application in the same area and site type.
Capacity model
The unit count the data supports for your site, given its size, type, PTAL, and conservation status. P20, P50, and P75 ranges so you can stress-test conservative and optimistic.
Viability table
Build cost, GDV, finance, CIL, S106, and land residual for each unit count. You’ll see where the affordable-housing threshold collapses your margin, and what your maximum bid should be.
Refusal risk flags
The specific reasons schemes like yours get refused in this borough: design character, amenity, space standards, transport. Each flag is drawn from actual Decision Notices for comparable applications.
Comparable case studies
Five to seven real applications for similar sites in your borough. Addresses, outcomes, unit counts, determination times. Approved and refused schemes with the reasons behind each.
Process intelligence
Median determination time for your site type, delegated-vs-committee probability, and finance carry cost at current rates. The timeline and cost of planning, specific to your scheme.
How it works
Tell us about the site
Address, borough, scheme type, target unit count. Two minutes on the form below.
We run the analysis
Your site is scored against every comparable decision in that borough. Risk rated, capacity modelled, viability calculated, refusal patterns mapped.
Report lands in your inbox
HTML plus PDF within 48 hours. Concise enough for a board paper, detailed enough to brief your architect.
Versus the alternatives
You already have ways to read a site’s planning risk. Here’s why developers use a Site Assessment alongside or instead.
Site Assessment
Statistical picture from every comparable decision the borough has made. Priced to be pre-acquisition, not post.
Pre-application advice
One officer, one scheme, one opinion. Sought after acquisition because the fees and timeline don’t fit earlier.
Planning consultant
One consultant’s judgement. Useful for strategy and drafting; not priced or paced for acquisition decisions.
Your own research
Council planning portals are not designed for developers. Decision Notices are scattered, unstructured, and unclassified.
Does it work?
Three numbers you can act on. Tested on 4,646 live London decisions the model did not see in advance.
Bid with confidence. Sites flagged Low Risk are approved. London average is 1 in 2.
Bid the right number. Capacity prediction lands within 2 units of the approved scheme 74% of the time. Six-figure residual, quantified.
Or don’t bid at all. Typical abortive cost of a refused application. One assessment pays for itself the first time it flags a loser.
Pricing
Per site. One-off. No subscription.
A refused application typically costs £20,000 to £35,000 in abortive fees before holding costs. The assessment costs less than your first set of drawings.
Questions
Before you make an offer, or during due diligence before exchange. The assessment is designed to inform your bid, not to replace your planning consultant after you’ve committed.
No. This is a data-driven intelligence report. It tells you what comparable schemes achieved, what the refusal risks are, and what the numbers look like. It complements, not replaces, professional planning advice.
Site address, borough, scheme type (conversion, demolish and rebuild, and so on), approximate site area, and target unit count. If you know PTAL and conservation status, include those too.
All 33 London boroughs. The dataset is complete, not a sample.
Each site is £1,000. For 3 or more sites in the same borough, get in touch for a package price.
